Exhaust gas heat exchangers - Import export

Engines for combined heat and power plants are operated with different fuels, including hydrogen, natural gas, biogas, sewage gas and special gases, plus diesel and other liquid fuels. In an exhaust gas heat exchanger, the hot exhaust gas from the CHP engines or CHP gas turbines is cooled, in the process heating water, a water-glycol mixture or thermal oil. This thermal energy can be used in a local or district heating system or for other industrial purposes.

What you can expect from APROVIS exhaust gas heat exchangers: - Efficient hot water generation in combined heat and power plants - Heating of thermal oil as an energy source - Individual solutions and compact designs - All the main components for the exhaust gas section and gas treatment are combined under one roof: proprietary products developed in-house - Cost-saving and reliable operation of the systems - Maximum functionality, safety and service - Temperature ranges: up to 600°C on the exhaust gas side or up to more than 1,000°C in the high-temperature range - Maximum functionality, safety and service - Temperature ranges: up to 600°C on the exhaust gas side or up to more than 1,000°C in the high-temperature range - Certifications: PED 2014/68/EU, ASME Code, EAC - Can be used in all plants with exhaust gases from hydrogen, natural gas, biogas, sewage gas and special gases, plus diesel and other liquid fuels - Geared to international standards and directives

This new addition to our product line is a compact heat exchanger made from high-alloyed stainless steel and can handle temperatures up to 550°C. Its compact and modular design makes it extremely versatile and easy to service. Our exhaust gas heat exchanger is designed to recover heat from exhaust gas produced for example by combustion engines used in combined heat and power plants. The heat exchanger transfers the heat from the exhaust gas to a liquid (water or water-glycol solutions). When heated up, this liquid can be used in central heating systems; for preheating air in the combustion chambers of furnaces and turbines; to dry coal, pulp, wood and other materials as well as for generating electricity with a Rankine process.

Exhaust gas bypass systems are made as additional equipment in exhaust gas heat exchangers. 3-way flap is required for bypass systems. By-passing the gas flow makes it possible to adjust temperature inside boiler (exhaust gas heat exchanger). Before delivery, we do a thorough test drive for every single damper, using actuator and special measurement equipment, to make sure that they function as expected and are ready to serve reliably on site. Availaible in steel, stainless steel or heat resistant materials Flange type and size depending on customer needs We develop dampers in different sizes and various temperature ranges Actuator options; Pneumatic actuator, Electrical actuator

Temperature exchange between a gas and a liquid In the case of air-water heat exchangers (also called gas-water heat exchangers), there is a temperature exchange between a gas (usually air) and a liquid. Finned heat exchangers can cover various areas of application: - heating and evaporating, - cooling and condensing as well as heat recovery. In this context, lamellar heat exchangers are also called air heaters or air coolers. Air-water heat exchangers are often also used as exhaust gas heat exchangers or flue gas heat exchangers in order to recover the energy from warm or hot exhaust gases. Lamella packs for a large exchange area In order to achieve the largest possible exchange surface between the air and the medium (liquid) within the heat exchanger, lamellas or lamella packs are attached to the pipe system.
